- Prgm: CRUNCH v2.3
- filename date, etc. Verbose
- / / /
- Usage: CRUNCH {du:}<afn> {du:} { [id] } { /Q | /V | /C}
- \ \ \ \
- source destination Quiet Confirm
-
- Items in curly brackets are optional (namely everything except
- for the filename). The two optional 'du:' specs may be of the
- form DU:, UD:, D: or U: where D is any legal drive letter, and U
- is a user code from '0' thru '15' inclusive. The colon must be
- typed. The first 'du:' specifies where the filename '<afn>' is
- located, and it should immediately precede the <afn> with no
- intervening blanks if it is used. If no drive is specified, the
- default (currently logged) drive is assumed. The same is true for
- the user code. The filename <afn> may contain the ambiguous
- (wildcard) characters '?' or '*' if desired.
-
- The second 'du:', which has the same form as the one described
- above, is an optional drive specifier where the output will be
- directed. No filename may follow the the second 'du:' - the
- filename will be generated automatically (see below). As above,
- if either part of the 'du:' spec is not included (or if the spec
- is left out altogether) appropriate defaults will be used.
-
- The resulting file will have the same name as the crunched file,
- except that the middle letter of the extension will be converted
- to "Z". If the original file's extension was blank, or already
- had a "Z" in the middle, then a filetype of "ZZZ" will be used.
-
- [id] is an optional "date stamp" (or other information), used to
- identify the file. If used, [id] consists of any text contained
- between a pair of square brackets (ie the brackets must actually
- be typed). The text contained in [id] will be recreated at the
- console for the operator's reference when the file is later
- uncrunched.
-
- Three command line options, "/Q", "/V" or "/C", are available.
- If used, the option should be last on the command line, and the
- "/" must be preceded by a space. Although the technical usage
- above implies only one letter may be used, rev 2.3 will accept
- any two options. Other combinations, which would include both
- Q and V, are contradictory.
-
- "/Q" and "/V" will "quiet down" a version of CRUNCH which has
- been configured to be "verbose", or cause a "verbose" run of a
- program normally configured to be "quiet". This relates to the
- amount of information sent to the console while the function is
- in progress.
-
- "/C", the confirm option, is used for selective crunching. Norm-
- ally used in conjunction with wildcard filespecs, this option
- causes the program to ask "Y/N" for each matching file. Only the
- files to which "Y" is responded will be crunched. Selecting this
- option causes the program to automatically ask for additional
- confirmation if a pre-existing file is about to be overwritten,
- regardless of the program's configuration.
- Prgm: UNCR v2.3
-
- filename Quiet Confirm
- / / /
- Usage: UNCR {du:}<afn> {du:} { /Q | /V | /C}
- \ \ \
- source destination Verbose
-
- All usage, options, and patches are identical to CRUNCH, de-
- scribed above, except that no [id] can be specified. Also note
- that the that the resulting filename will be recreated from the
- name of the file that was originally crunched.
-
- It is not necessary that the file to be uncrunched have "Z" as
- the middle letter of the extension; an attempt will be made to
- uncrunch any filename explicitly specified. Note however that
- "UNCR *.*" will be internally converted to "UNCR *.?Z?" to facil-
- itate quickly uncrunching all crunched files in a mixed group.
